I have a ton of replays and would like to post them/get rid of them. Is there an easy way to a boat load of replays without the individual file choosing and what not?

You could compress a whole bunch of them and upload it as a downloadable file

If you want to upload them using the forums, you can only do 5 a time and you have to select all of them seperately.

Using sites like MEGA or Mediafire, you can, in most cases, select multiple files and upload them all at once, then paste the link somewhere you want it.

Put them all in a. zip file and upload it either directly or through some third party site like Dropbox, google drive, or mediafire.
