There is however one problem that prevents me from giving it the very best rating:
I have a few menu items with sub-items that are always expanded by default (i.e. sub-items are always shown). Xmap gets confused by this, and the result is that these sub-items are listed twice. First they are enumerated as sub-items of the parent item, and then the sub-items get counted again. This may not be an excellent explanation, but try it yourself and you'll see what I mean.
Overall, a very good extension that works great and is highly customizable.
I wanted my visitors to have the ability to leave comments on articles, including guests (users who are not logged in). To prevent comment spammers from abusing this, the need of some anti-spam measure was obvious, and yvComment supports at least two different Captcha plugins (separate extensions). I managed to get everything up and running the way I wanted to in less than an hour.
If you're interested in such functinality, yvComment is great. Be sure to read Yuri's instructions on his web page first, though. I believe it would have taken me a great while longer to figure everything out if I hadn't read the instructions first.
Thank you, Yuri!
