A very handy tool, especially when providing support to clients - you only have to ask for access to Joomla administrator, without needing separate database access. Nowhere near as powerful or complex as phpMyAdmin, but the essential features are there and it is dead easy to use.

This is a nice component for simple reciprocal link management, however it is littered with many PHP notices which render it virtually unusable unless you turn off notice reporting in PHP. This reflects a somewhat sloppy approach to development, and raises concerns over the quality of the programming.

Otherwise, the features are nice, and presentation overall is good - it should fit into most site templates without much tweaking being necessary. There were 3 features that I would really like to see added:

1) Nested categories (you can only have one level of categories at present)
2) Given that the whole point of reciprocal linking is usually to improve search engine ranking (albeit the importance of reciprocal links in this has now diminished significantly), the ability to specify a number of titles/descriptions/URLs for people to link to - perhaps publishing one chosen at random from those available (eg. you get to define 10 different links to different parts of your site, and when someone wants to exchange links, the component would pick one of those at random for the user to publish on their site).
3) For the same reason (SEO), it would be nice to allow a title attribute to be defined for the link.

More advanced features could be added (eg. allowing a logo upload), but I think the above 3 are the most important.

If your requirements are for a simple reciprocal linking system and you don't mind the lack of SEO features (or you can tweak the component to improve them yourself), this component will do the job. For now I am sticking with a modified version of Bookmarks.

Looks promising, but the lack of documentation is a big letdown. Even the forum does not provide anywhere for general support queries to be posted. The component front-end failed to display properly for me, and the module would not allow users to unsubscribe or change their preferences, making it unusable.
