I don't know when how long there is left to vote, but the semi-official Touhou popularity poll for this year is open for voting.  Aside from Characters, there are also categories to vote for for favorite music and game

The wiki here details how to vote and provides links

While I think I have a good avatar for our group picked out, I am once again pulling my hair out trying to get a good banner that doesn't come out like garbage.  If anyone in the group has a good idea for a cover, feel free to leave it here and we can take a vote on if it looks good as a cover.  The current cover is just a close up of Reimu's character symbol and was the only one that came out decent before I gave up for the time.

Of course, if anyone thinks the current avatar isn't, feel free to leave a suggestion and we can decide on which we like better.  I took the avatar from Reimu and Marisa's combo attack from the last Fantasy Maiden Wars game (see below).  It seemed to fit, since they are the two main characters.
