I'm really not sure how this rumor got started; LimeWire has always supported resumed downloads! Here's how it works:

If you are downloading a file, and the server disconnects you, LimeWire will automatically try to resume the file. If the resumes don't work after several attempts, it enters the "Couldn't Download" state. If you hit the "Force Resume", LimeWire will try the resume process all over. If you kill LimeWire while the download is in progress, LimeWire will try to resume the download next time it runs.

Now, if you have several hosts in a download group, LimeWire will even try to resume the file from another host in the group. If that file couldn't be downloaded, LimeWire will try other files (e.g., with different sizes or names) in the group. However, the original download attempt stays in the Incomplete directory for your convenience.

Here's what LimeWire can't do. First, LimeWire does not provide a way to re-search for a file and add that file to an existing download group. It may do so in the future. Secondly, it doesn't support resumptive push uploads. That's not really a problem, since the push route will have expired by the time you get to resume, but we'll implement it in an upcoming version.
