You're not causing problems honey - a lot of us came here with no idea what we were doing so we've all been where you are.
You seem to have managed just fine and I see all the details in here so *hugs* good on you for getting there! If it helps, I just go to the actual entry itself and there you get the little picture buttons at the top - then click on edit entry.
Since you're new can I point you to our sister asylum run by EKP - those girls are so awesome they even have tutorials for newbies like us that you might find helpful http://asylums.insanejournal.com/eskimo
And a lot of us use Semagic (spot the person who hasn't downloaded it to new lappy yet :P) to help with the tricky matter of HTML to create links anf formatting. It's out there free to download and a lifesaver!
And welcome again! Grab a drink and a spot on the sofa. Hope you enjoy looking around and don't be afraid to ask if you're stuck. Our details/email are in the user info if you ever need us ;)
