Hello BCAD, welcome to AOTK
Noticed in the Spank Note RP recruitment thread that you were worried about a limit on the number of PMs. When I joined AOTK (very soon after it started) there was a maximum of 50 PMs, this later grew to 500 and now it is 5000. I think your limit will increase when get beyond being a Protationary User so I don't think you need to worry about running out of PMs.
