And don't worry about making mistakes at first, Most everything can be corrected without a great deal of knowledge. But bear in mind that the sooner you correct mistakes, the sooner you can get on to adding more new material. I don't know how you usually do things, but I spent about equal time adding new profiles and reading the help files for the first few months here. I also tried finding questions to ask here on g2g both to find ways to do things and to find out if I was entering people the right way.
