ponygirl,
Not sure of exactly what you are asking but...
re: content:
In order to keep getting accepted at LL's you are going to have to have some diff content for diff sites
re: old sites:
I "spruce up" older sites as I come across them... Yesterday I found a site that was circa 1998...... old recips, crap html etc etc.
So the recips got re-jigged, html got cleaned up, and I will get to re sub this site to multiple LLs.
re changing sites:
As for changing existing sites that have no problems... hmmmmm I dont think anyone sets out to go back and change things... its easier to build another.
hope one of the answers fits..
