UniBall Central does not pick and choose the maps. All maps that are sent will be placed on the page unless they don't work, or don't follow the guidelines.
Once a map is submitted to UniBall Central, it cannot be removed!
A revision or modification of a map will be accepted - however, they will take the place of the old map, and they won't be mentioned in the update. The map will simply be updated, but since it's a revision, it doesn't warrant a mention. This is to ensure that only the latest version of a map is present here. A revision/different version of a map you are not the author of will not be placed on UniBall Central. Also, a modified version of a map for offline play will not be accepted. Make your maps playable offline.
When sending your maps, follow this format!
The subject doesn't matter, just make sure that I know it's a map, and not some demented form of spam.
In the body of the e-mail, use this format:
Map Name: (the name of your map - this is exactly how it will be listed on UniBall Central) (if it's a revision, please note) Author: (author) Type: (hockey, dodgeball, "racing", or some other type)
If you don't follow this format, your map(s) won't be placed on UniBall Central. By submitting your maps to UniBall Central, you are automatically giving UniBall Central permission to place your map(s) on the page.
Oh, and why not take the extra twenty seconds, and make sure to fill out the map information in the map itself? (Open up UniMap, and click on the "Map Settings" menu item at the top, and fill it all out). If you don't, you're going to have problems when it is reviewed - the default number of players is 10, and that may not be a suitable number for your map.
Also, feel free to submit any maps you wish to be placed on UniBall Central. You may send them to Frog@uniball-central.com. All player submitted maps will be placed under the third category, unless they have been on the UniBall server. Note: View the guidelines for map submissions. Submissions that don't follow these guidelines will not be placed on UniBall Central!
If you have a review you wish to send in, feel free to send it to Frog@uniball-central.com. However, take note that reviews will be read before they are uploaded. If it mostly consists of plain flaming, without any reasons to back it up, it will not be posted.
