Module development and code questions

I recently installed the events module however whenever I set an event it changes the start time to
1970-01-01 00:00 that is in 1970, and the time isnt even right! Anyone who can help please assist me with this problem.

In regards to a previous discussion on 'XMLNode' I've been looking at using the 'filters' mechanism to do XSL processing.

... And it works, sort of.
I created a filter definition (easier than I thought)
I declared it as an input filter (which isn't where I want it to go, but seems to test well)
And I can paste in raw XML content, and it displays as parsed results.

... but the parsing happens each time! The raw source is saved raw (which is actually a fantastic feature) but this is not what I wanted or expected. Is there a way to apply an IMPORT filter, not an EXPORT one?

Seeing as my target is not in fact to apply the filter to the input textarea, but to content from other sources, would I be best to branch the 'filter' concept into a whole other interface to administer the pipeline similar to that described by gjost?

Specifically, what I've got so far is an XSL that scrapes & converts HTML pages (head, meta & all) to a structure like the import/export module produces, which is then ready to be made a node.
I want to tune the pipeline (which will be needed for different pages coming from different layout schemas) and I think cascading filters will be cool for this, but then again, they may not be approriate, expecially seeing as I am wanting to end up with structured information, not just a string.

I want to be able to classify my nodes in a way that allows a node to have more than one term from the same taxonomy.

As far as I understand, the current taxonomy systems allows me to select one term per taxonomy by choosing from a select box. I would prefer a way to choose from all terms from a set of check boxes.

Is there a way of tweaking the taxonomy system to use check boxes?

Maybe I should try to create a module of my own to do this, any suggestions?

Has anybody done this? I'd like to have a single table row with an autocomplete field in it for an "invoice" style node, but of course you need to be able to add more than one row.

Just trying to avoid reinventing the wheel ;-)

I have 2 variables (A & B). Multiple A's relate to a single B, and multiple B's relate to single A. Occasionally, I'm going to have to pull a list of B's when given an A, and sometimes, I'll have to pull a list of A's when given a B. I'm trying to figure out the best way to setup the table. I think this way would be the easiest for future queries, but I'm wonding if it will end up being too big when I have a few hundred B's and maybe 1000 A's (meaning there would be up to 1000 rows. What do you guys think?

Has the Email Page module ever been upgraded for use with Drupal 4.6? I would really like to implement this module but haven't been able to find a 4.6 version. Does it even exist?
