Module development and code questions

Hi,
We are doing an e-commerce project for a client. He wants to use http://charge.com as his payment gateway for his online e-commerce transactions.
Any one knows about how to integrate charge.com payment gateway ? Please give your suggestions.
Thank you.

I have been trying to make captcha 4.6.0 work for comment under Drupal 4.6.5, but I cann't see the image when posting comment. However, the comment will be rejected because the text doesn't match. Can someone please point me to the right direction?

Is it possible to find out the order of hooks calls when a page is called? Is there a rule or function that determines this? Is it immutable and dependable information that can used in the creation of a module?

I am asking here rather than on the mailing list or icq because I need to be able to refer back to any information given.

Hi I'd like to update a module (donations) from 4.6 to 4.7, but I keep getting the following error:
cvs -z9 -d:pserver:lapurd:password@cvs.drupal.org:/cvs/drupal-contrib login
no such user lapurd in CVSROOT/passwd

Never had any CVS problems before, this seems a problem on the server. Anonymous works fine. Anyone can help me? I've looked around for answers on this site and Google and so far it seems related to the server. Thanks.

Is it possible to find out the order of modules being loaded when a page is called. Is there a rule or function that determines this? Is it immutable and dependable information ?

I seem to remember seeing that modules are loaded in alphabetical order. Is this true? Would it be safe to say when a forum node is called then

Comment
Forum
Node

is the order? or would it be something different everytime?

Is there in Drupal any function that does something like this ??

function path_returns_alias(drupal_path)

return alias_for_drupal_path

This could be useful to 'mask' original paths with aliases (if they exist)

For example, instead of taxonomy/term/1 if I defined the alias 'category1' for it, whenever I don't want to print out taxonomy/term/1 I would prefer to print out 'category1'...

Hope I could explain....
