Place a stone for vote!! is the best way for rememeber to vote for Sylvan Heart !!
Sounds like a good idea to look into! :)
I played on one shard that had it as a grand father clock that told you if it has been 12 hours since your last vote. The clock also doubled as the link to the voting sites. Don't know how hard it would be to make... sounds complex but it was kinda cool.
As long as we dont login in through connectuo or one of the other sites like that, we should be ok. I think uogateway used to have it if they found out you had a vote link in your shard itself they would remove your shard from their list.
