Module development and code questions

Hi,
I am currently using the Replacement Tag module (reptag) for replacing {USERNAME} with the actual
username of the user dynamically.
But the module is not functioning correctly and I am only getting anonymous as the output for all
users irrespective of the username that one logs in with.

Can anyone help me to get it working as I am very much in need of this function URGENTLY.

Any help would be appreciated as long as it contributes to the working of this module correctly.

I'm getting desperate trying to find some way to filter nodes with empty date fields (a IS NULL query for the date field of a table). I have a content type named "projects" and I need to generate a list of "active" projects: those that have been started but haven't been finished yet (in other words, those that have the "Ended on:" date field empty.

I've been playing around with the operators trying combinations like IS EQUAL TO IS NULL or IS EQUAL TO 'IS NULL', and even IS NOT EQUAL TO '%' without any success.

Can anybody help?

Hi, I am looking for a module that generate .txt file from node and enclose the file as attachment to the node.

The attachment file must be the same as node. So this is for the users who want to download the node locally on their computers for further reading.

Thank you.

I have defined several discrete taxonomy terms to which content is posted. For example, I have taxonomy terms such as Humor, Action, etc. When a user posts content, he/she is prompted to specify what category (taxonomy term) said content should be classified under. When the content is submitted, it is posted in the appropriate taxonomy. When a user desires to read all the "Humor" content, he/she simply navigates to that page and all the relevant content (multiple nodes) are displayed.

Hey all, I'm looking to build a site for a client and I need a module that will allow visitors to the site to submit questions which are inserted into a queue, which the admins can view and answer and publish to the site. Is there a module which supports this?

I recently installed the ldap_integration module and after a little bit of looking, was able to get the groups to carry over great from an Active Directory server, but if I add or remove a group to the user in Active Directory, the updates are not reflected upon the next login to the Drupal site.

What it looks like, is that when a new group is encountered, the new group overwrites the last existing role and then a $rid of 0 is added to the user's roles in. I'll try and track it down, but in the meantime, has anyone else encountered this?
