This is my first time roleplaying, it would be nice to get to know the ropes. Can I have some pointers and the do's and dont's of roleplaying so I don't make any noob mistakes?
Besides doing the obvious and reading the Rp and Site rules...
My first time RPing, coincidentally on this very site, I wish I would have known to be more comfortable with asking for help or to RP with someone else. It took me a little while to get into the thought process that nearly everyone is willing to help if you just ask. Set up an OOC thread, where you can ask other RPers if they are interested in (insert idea).
Or have a conversation with someone that comments on a character profile or someone that generally looks like they'd be a good fit for your character to RP with, and ask them if they would be interested in a ROle aplay with you.
Hopefully not everyone will be too busy on New Timeline projects to get a RP going with you. Alas, I am one of those people that will be preoccupying myself with projects :(
Welcome to the site and our section of the interweb @Melomex! We are about to shift to the start of a new timeline so I have announcements that have been released for it. Below is the link for the announcements as well as some role-playing help threads for getting started.
