Dear JanePlain,
Welcome from a simple closet crossdresser who is also fairly new to Susan's. I've found a lot of things here that are wonderful and have helped me to a more complete understanding of who I am (and, come to think of it, who I am not).
If you explore the forums a bit you will find things that you'll want to comment on, sharing with others your personal experiences. And they will appreciate it. And occasionally you'll think of something that you want to learn more about and you can start your own thread and see what other people have to say.
Its also good to wander through some of the introductory stuff. You can learn things there -- among which is the "post count" that moves you up in "status". Once you have posted a certain amount of times (15? 16?) your "status" changes from that of a visitor to that of a newby member which opens up certain privileges to you.
So welcome to Susan's, we're happy that you have decided to take the step of visiting us and we hope you'll stay around for awhile. Somewhere here you will find something that will feel just right to you.
Carolina
