Summer is usually a very slow time for RP on Atlantic, so the RP community may not be as visible until things pick up again in Oct.
There are still weekly tavern nights at the various roleplay taverns on the shard, as well as semi weekly/monthly events and tournaments being held.
Right now there are around 50 RP guilds of varying sizes, the current largest ones being MTC (based out of Moonglow), Umbra, Sanctus (the area near Hanses Hostel), as well as several others.
If you need more info, their forums are located
