I will see if I can figure out something to connect people.
I haven't been watching the IGS, since I haven't been playing and I was typically one of those "don't talk shit on IGS if you're not gonna be in space shooting/being shot" types... my understanding is that with the free accounts/alpha clones, I'd have access to post even though I'm not playing at the moment, and that temptation may prove great enough that I choose to stay away altogether.
I don't know Miz very well as a character, or you as a player, but some things I always wanted to try that would not have fit well at all with the Havohej character and which you might (or might not) be able to cherry pick an idea or idea seed from:
Pseudo-science articles/reports of any type on a topic or topics relevant to the Minmatar as a whole. For example, a sociological thing about the differences and interactions between the different Tribes, an article along the lines of "Integration of the Starkmanir/Nefantir: X Years Later", maybe criticizing shortcomings in the way the Republic government has maybe fallen short of those peoples' needs, offering solutions, who knows, whatever you want your character to say. Whole thing was much too humanitarian for a terrorist like Havo, so I left the ideas on the shelf. Expected things like that to come out of -EM-, but (to the best of my knowledge, having been away for a while) I don't think any of their more prolific writers ever got around to putting together another one of their fucking fabulous pdfs. (Electus Matari pdfs were huge for me when I first started getting into Eve RP, and Eva, Killjoy Tseng, Arnulf Ogunkoya and all those cats were all top class people to interact with, even as enemies).
Charity events - pool some ISK together, get some shiny stuff and hold a big event where raffle tickets are sold, or a charity auction (though that's been done before, depending on timing there's nothing to say that only one person in the entire cluster can hold a charity auction). The key is for it to be geared toward raising awareness of "Minmatar-focused thing that may or may not have anything to do with war - say, shitty water quality/living conditions in Molden Heath for example (which sounds right up a Shaman's alley to want to do something about)" and bring people together who otherwise might not ever find their characters in the same room to interact with each other. I think it was Stefanie Sessorie (I didn't spell that right at all) who held the one I participated in where I apparently was in a bidding war against Silas of all people - which was a damn fun time, and fun interaction with several IC enemies including Silas.
Those are just two ideas, if I wanted to REALLY text wall I could go on a bit more. One thing to keep in mind is, and again I'm not super familiar with you so for all I know you might already have quite a catalogue, but the thing is that there are so many really wide gaps in the PF that we have, don't be shy about making shit up. If it sounds feasible to you, run with it, and people will choose to interact with it or not. For instance, I used to have a fiction posted to a blog I used to have, that would more or less act as OOC background so that players interested enough to read all that in addition to the IGS text walls I'd post, would have more of an idea exactly what it was they were interacting with then deciding to accept Havohej as an enemy by engaging with him on the IGS and/or in space. My worldbuilding was never on such a grandiose level as, say, Saede Riordan and all that she's done with her Origin star system, but I like to think it was clever and gritty enough to support Havo's "edginess".
Anyway, yeah... I'd love to see a big resurgence of Minmatar RP and if I had both the time and a suitable machine, I'd love to offer a bad guy as per Scagga's suggestion. With a suitable machine, I might even be interested in taking up a more moderate Minmatar character and exploring Arnulf's idea with him (and I wish you the best of luck, Arnulf!)... I just can't right now
Hopefully something in one of those two thoughts offered can nudge your own creativity in a helpful direction!
