Congrats! I did the same as ^^.
Although after the first few weeks, I pretty much just listen to the repeaters now. A) I don't really have much to say. B) I talk on a radio all day long. C) Some of the chat is very technical and waaay over my head.
Once you do dive in, people are very friendly and helpful. Don't be nervous to ask questions.... it's a great community to be a part of. There are some very knowledgable folks on here too.
