I'd like to remind people to please update their version of Articles to v1.03 if they have not already done so - this update includes an important security fix.
If you are at all worried about the security of your site, then the Protector module by Peak XOOPS is highly recommended.
I would write a security guide regarding XOOPS, but the chaps at XOOPS tips have already written a good one, so why reinvent the wheel? You can read it here.
Finally, I would like to state that I am dropping support for Articles for anything other than serious bugs (which is unlikely as it has proven to be quite bug free in general, this is only likely to be a problem with new versions of XOOPS) and security issues.
By all means, please ask in the forums if you have any questions about its use, or want to make modifications, etc., but please do not be insulted if they go unanswered by me. Direct e-mails to myself probably won't be answered either, unless I have time. I do not mean to be rude, but I am very busy with various things, plus I have 4 other modules that I am working on, and trying to get Articles v2 started, which will have loads of new features v1 does not have.
