I love this idea! But instead of giving out paid accounts for birthdays, why not give it out to muns/characters who tag out the most? It will still be voluntary if we make the muns post their own proofs and we can award it to the one with the most, every month or so. It's fair and transparent. It's in no way required, but if people would like a paid account then they can get it by tagging out more. We can work out the details like tags into closed logs don't count and/or you can't keep tagging the same character repeatedly. The gist of the idea is to make people branch out more and get a little reward in return.
