I want to do some changes to my server, but i want to know these. 1. I know a guy with a name starting with icrispy or something, is he a good developer? (Please forget about price) Is his skywars plugin stable? 2. Is popup a new feature on 1.5, or is it available through 1.4? 3. Is PM 1.5 required for people to join my server with the MCPE 0.11 and vice versa? If not, what could have gone wrong? 4. Can you let players with 0.11 and 0.10 at the same time? Thank you if you can answer these in detail, preferably in a noob way.
