Module development and code questions

I am trying to make a script I wrote in the past into a module. This script accesses a database other than the one that Drupal uses.

For my first attempt I got an error:

Fatal error: insert command denied to user: 'floraforumread@newdelhi.flora.ca' for table 'watchdog' query: INSERT INTO watchdog ...etc...

I am currently attempting to port the TikiWiki JGraphPad drawings 'module' to Drupal 4.4.1. (I am liberally using code from the node_image and urlfilter modules -- many thanks!).

Sorry if this is already known and fixed, but in the version of the "Quote" module I just downloaded, there was a tiny bug that completely messed up my site: When using the quote tag without an author, an (I think) extraneous close div tag destroyed my layout.

I located the close div tag in line 70 of quote.module

If anybody knows whether deleting that tag will cause further problems, please let me know. So far it seems to have resolved the issue.

I'm having trouble updating 4.4 CVS tags on modules and themes in the contributions repository.

I've done a modified version of statistics.module that supports browser and os statistics.
The download is avalaible on http://assente.altervista.org/?q=node/view/19 ; the site is in Italian but the module is in English.

I had an interesting idea that might make a good Drupla module. FreeCache is free service at http://www.archive.org/web/freecache.php which will cache contant for free. It's kind of the poor man's
Akamai. What if there was a Drupal module to enable the munging of selected URL's on a Drupal site to be fetched through FreeCache, or some other caching service.
