Well Razek, i have a few things to say about that case.
Firstly: If you feel your charecter isn't getting enough attention, ensure that he/she is well constructed and attractive to Roleplay with.
The more orgininality and roleplaying possibilities your charecter has, the more people will want to roleplay with him or her.
Also ensure that your roleplaying is flexible enough to actually allow people to roleplay with you.
Apart from this, my main opinion on this case is:
Find a RP with a better DM.
It is the DM's job to make sure the roleplayers are having fun. If the DM fails at that, he fails at DMing.
If you're in a RP and you're boring your ass off due to the lack of attention your charecter is getting, find a DM that can spread the attention and plot elements properly around the charecters
I have seens alot of DMs on the hive (i'm not gonna' mention anybody specefic though) that makes a RP thread, creates the setting, accepts the charecters and then just sits back and only interferes if somebody is being a jerk-ass or does something that doesn't fit into the DM's rp world.
These DMs play in their RPs almost like normal players, and do allmost nothing to ensure that everyone is having fun.
They don't set up plots and stage events that the players can play though, they just leave everything to the players.
They don't help newcomers into the RPs and they don't ensure that everyone gets to have that "Epic!" feeling that makes RPing worth doing.
Such RPs end up being like advanced games of RISK, and yet with notirously less rules.
I don't know about you guys, but this annoys ME.
