Alright. Currently, no. But I'm hoping people will play nice and when they see posts like that, don't go out of their way to pull a dick move and claim a pokemon someone else has already publicly expressed interest in. If it starts to become a problem, I'll look into making a rule about it, but until then, you can "sort of" reserve a Pokemon, but it won't be official.
Whenever a new slot opens up, the first to post or PM me about it gets the slot. Everyone else who misses it but still makes a post will get a PM from me when another slot opens up so that they have a higher chance of posting before anyone else. (I do this so that slots can't be reserved while the list is full. But for those who are eager or have been waiting a long time can know exactly when another slot is going to open up and have a higher chance of being able to grab the slot). I hope that answers what you were asking. :O
