Module development and code questions

Since 4.7 we now have a super cool autocomplete tagging system when we create nodes.

What I would really want is that EVERYONE (or at least, registered users) be able to tag content, BUT the system would remember who tagged what and provide a 'my tags' and a 'others have tagged this...' for popular tags (let's say 5 or more people have tagged it the same name, to avoid spamming).

The autocomplete would search all tags (and maybe even find synonyms?), in order to minimize different tags.

Hello,

I've been looking for a module that would allow me to content (full HTML) to a block that I can then push to the right or left sidebars. Essentially, the content will be release date information. It would be fantastic to have a module made just for it, but I lack the proper skills to build a module to do what I'd like it to do. So the next best thing would be one that allow for me to title the block and then put content (full HTML) in it. Does anyone know if one exist? I suppose the best route would be to try to code one myself but that seems near impossible.

I am making my site as a kind of MySpace or Xanga, but just for my university. Some of the groups involved would be student orginizations, and of course once the predsident graduates, you would want to be able to pass ownership onto someone who would still visit the site. I was wondering if there was a way for one or more of the following to happen:
1) The current president to pass ownership of the group to another member of his choice
2) voting on a new president among current members, or

i am trying to write my own module. i didnt like the way taxonomy lists categories so i added 2 selectboxes and update the child with XAJAX. everything works fine. but if i submit the form i got an error saying :

An illegal choice has been detected. Please contact the site administrator.

Sorry I can't find this kind discuss and info in Handbook,
so i want to ask,
If drupal support C/C++ extension or API,
let developer can write modules with C/C++ ??

Thanks

I am trying to work on the little known directory module and I want to take a tree object that comes from $tree = taxonomy_get_tree($vid); and turn it into a menu uls and sub-ul's like drupal does with it's menu system. I feel like that gives me the most flexibility from a layout perspective. So I would have ul, li, li, li then if theres a submenu I'd have a ul inside one of the li. Anyways it's probably like one function call or something. Thanks
