Welcome and well done on taking that first step. Please don't feel your joining Locs will somehow throw you out in the big wild lesbian world ;p...
It really is a good way to find safe spaces for socialising and meeting like minds. Coming out can also be made easier by having a circle or forum to share the difficulties you encounter on your coming out story.
Having said that, you must do what is comfortable for you and I do hope to see you at a LOCS event soon. We are friendly bunch.
