and the readme:

Security: The password database is stored in the clear. While it would requ +ire a local account and some ingenuity, I strongly suggest you NOT reuse + any of existing password. I am not going to explain how, but it is also +possible for a "bad" person with a local account to wipe out the database(s +). If the project gets a following, I will take steps to mitigate the ri +sk. Stability: This is extremely pre-alpha and buggy. It was my first attempt at +: Parsing XML Using MLDBM Generating HTML (as you can see by this readme.txt) etc. Names/Passwords: Accounts are on a first come first serve basis. If you have forgo +tten your account/password, you can try /msg Limbic~Region at PerlMonks +. You will not be notified if your login credentials are incorrect. + You will simply be returned to the login screen. Reports: There are currently two options for reports. One allows you to ge +t any new replies for a thread that you are tracking. The second allows + you to get only direct replies to the node. An important thing to realiz +e is the database will be updated for all children regardless of the re +port. This means if you first try "direct replies" and then "all", you w +ill not likely get anything on the second report. Even if you do, it +will only be any newnodes that were added since the last report. If de +sired, I can fix this. Content Change: Currently, there is no way to determine if a node has changed with +out storing a checksum. This would require recursively going through +all nodes in a thread to determine if there have been any updates. I +don't think the added strain is justified. If this changes, I will like +ly add support if this project gains popularity. Load for PerlMonks: Every time a user adds a node to be tracked or generates a report +for a tracked node, two calls to PerlMonks is made. If the "gods" deter +mine this is too much, the project will be shut down immediately. Bugs/Patches/Comments: I am sure there are a lot of bugs. All bug reports, patches, comm +ents, and suggestions are welcome. /msg me at PerlMonks License/Copyright Copyright Joshua Gatcomb 2003. License same as Perl
