Hi NMcM,
I fell a bot at your point. I went into this field through Indexhibit, and feel the needing of learning the basics. It happens to me something similar than to you. I understand I should edit something of the files they talk about, I started to undrestand how the language goes through the tutorials about css or html, etc, but...... hhhooowww, do you customize those archives? I read carefully lots of times the few threads about it, and the farest I went is:
What we should modify is in the FTP thing, in my case at Cyberduck. I realized and found the archives they talk about, and the farest I get is to double click on them and see that there is an option that says 'Edit With >' and after that I see that 'there is no external editor available'.
On the other hand, I downloaded an editor (called TextWrangler) and opened the style.css file from outside the FTP, and It opens, you can see there all what they talk about, and also modify it (customize?).
Then, If I can modify that same file from out the FTP, why I cannot even open the one wich it is inside the ftp.
But we are getting closer.
By the way, I am still stopped in something dummier, I cannot do new sections or exhibitions on my site. So I still have only two, the ones from the beggining. I wish somebody could help me with this.
Good luck and thanks,
kenneth
