I know you only get 50 which is wrong! But make a habbit before you send a message to be sure there is room.
I hate to use names but got a PM from i guy i wanna talk to... Another mailbox full. Its frustrating and takes time. Scorpio can they get more spaces? Or an alert telling them they are almost out of room? I prolly missed out on a great guy cause i didnt reply he thinks im a bitch for not replying!
