Mogrify or Something Else?

I want to create watermarks on my photos in LR2 on my PC, and was told by a friend that Mogrify was the hot ticket. When I did a search on this forum, I see some people use it, but I see some errors associated with it. Maybe those are nothing to be concerned with, but I figured I'd ask about Mogrify and see what's up.

What's the scoop on Mogrify? Is there something else like Mogrify out there?

Mogrify has certainly been the tool of choice for Lightroom users, although LR3 has added more built-in capabilities.

I haven't heard of serious issues with Mogrify.

I've never had errors or issues with Mogrify. There's nothing better that I know of.

been using it for about 1 1/2 years now. updates frequently, and works with LR3 error free for me so far. i beats the pants off of the stock ability of LR.

I had a problem with Mogrify when I first tried to use it. But that was because I hadn't read the installation instructions properly. I'd guess that most of the reported 'errors' are the same.
