I think text messages are taking it a step too far from the current state. Personally, I feel that email would be the best way to accomplish this. And I think COE's newsletter format for TMs is perfect.
And I know all of us have weeks where we're more busy than others, and perhaps a TNP newsletter--whether it's for the RA or on a broader scope, for all forum members--via email every week, or bi-weekly, would be a way to encourage participation not just in voting, but across the board.
Instead of just saying hey, election's up, and having people "show up, vote, then fuck off again" perhaps an emailed forum newsletter highlighting the most active threads, or crazy IRC quotes or whatnot might be just the sort of thing we need to remind people that we're here, and that things are happening that aren't just "boring" proposals and votes.
In truth, I left for so long because things on the forum lulled, or the people I interacted with the most - my friends - got busy and I went to find other distractions. We all know the internet is an easy place to do that. And a few days turn into a few weeks, and then months, and years and so on. My email address was completely up-to-date on here, but not once in, what, two years since last time I was around did I get a notification from anyone about anything going on here, and I didn't give half a thought to this place until I was bored with my internet distractions and went, Oh yeeeeeahh... NationStates. OH YEAH! TNP! and ran back to see what was going on.
If we want members to participate more actively here, we need to have some more active outreach. A link on the WFE is basically a revolving door. We have people wander in and poke around and try and figure things out themselves, and most of the threads that show up on the front page of this forum lead to obscure political discussions where everyone seems to be angry at each other. Come on, that isn't exactly the warm welcome and happy atmosphere that leaves people inclined to stay and get to know us.
The reason I got as involved as I did, back in the day, and the reason I made so many friends over the years was because on the old old old forum, when I showed up, people said hello back, and interacted with me. I got PMs a-plenty with offers to answer questions or point out topics of interest, or other players I might like to interact with. And I dove in and made myself comfortable. Granted, not everyone is as wonderful and enthusiastic and easy to get along with as I am, but there's got to be a better face to the public than making them feel like they walked in on a rather dour discussion that they should just back away slowly from. Because that's the vibe I've gotten everywhere but the OOC since I've been back, it's like I've interrupted some angry shareholders' meeting.
I think an email newsletter might be a great outreach effort and a much-needed first impression makeover for this place.
