The biggest complaint I've heard several times so far, has been the confusion during setup. People are perplexed by editing the script and having a configure section in the program itself.
I will rework this and the docs before the first release.
If you submit more than 10,000 urls, the 10,001 url splats the database and errors on 10,002'th url. The database remains intact, but further submission is impossible. You will need to put the database into a editor, and "fix" the 10,001 url by hand (fake it). It works ok from there on out. I have not tracked down why this is yet.
Submitting to AOL Netfind causes a general submission error and no other urls in the current batch are submitted. This stems from the fact, AOL Net find no longer takes submissions for Excite, but has switched to Inktomi.
I'm hoping that I can wait until AOL takes Inktomi submissions before releasing the next version.
