do you have any senior slots available?
Slots 1-30 are for full, senior, and hero members. Slots 31-50 are for hero members only.
Slots up to 48 have been filled. Can you guess which members the last 2 slots are for?

Or OP could make the front post clearer instead of using a condescending tone when replying to people who are interested in the same campaign as you are in.
