I think what Andra means, is that in WoW you may have random encounters, in RoM you don't. There are so little rp'ers so to get them together to play needs a little planning usually. Out of character planning is welcomed and the guild channel is a good way for that. You may also plan (some beginnings) with another player in whisper and surprise other players with it together.
Ask ideas from older members. You could play Iarnas long-lost brother or Meines illegimate child or, with a cuckoo twist, both. If this agrees with the other player, it is easier to join the storyline. Or you can ask what kind of services other characters needs. For example Andraliel might be goinging crazy and there is need for exorcist and you could be that person. You can also send an in character message to one of the other chars and say you are in trouble and need rescue. You can also ask IC help to do ingame things, if you wish.
Don't be scared if the characters are rude to you. There are lots of chars that hate different kind of people for some reasons. We have racists, sexists, elitist and what not in our stories, so it's just good rp if you feel unwelcomed from those scenes.
We mostly do drama rp, so it is important how your char is alike. One whole scene can be just clashing of two different chars minds.
So ask, and you shall recieve. Play and whole guild plays with you.
