Last time I tried to edit the front page where it says "Congratulations! You have successfully installed your Zen Cart™ E-Commerce Solution." I totally took away my whole site. I had to start all over again. Now I thought I would ask first before I do it again. ah duh... can someone please walk me thru this editing..

where is it again that I do edit that text and please show me exactly how it should look like. I'm sorry but i do not know css and when you should have : and ? and such.. when I edited last time I just took out that statement and when i did so i lost everything. I thought it might be because somehow I had no bracket or something like that, as if I left something off but I looked and looked and couldnt see what I had done so very frustrated I deleted my whole data base and started new. well here I am again at this point ..
Sorry if this is you millionth time explaining but I have looked and do not understand..

also where is the area for editing " Tagline Here" on the very top of my page

my site is at http://www.outlawwomenscrapbookemporium.cn

someone please advise.

Thanks
