How do I send you my records? I can't find any link?

You don't. The site is fully automatic, there's no need to e-mail me with .rec files and telling the time for every record. You first need to register in order to upload anything. After you have registered you will then have access to the user page, where you are able to change your information and settings, as well as upload your replays.

Can I only upload a replay if it's a best time or a top10 time?

No! As long as the replay is for one of my levels and you are the driver, you can upload it even if it doesn't make it into the top10 list for that particular level. When you click on a level name in the lists, it takes you to a detailed page with information about the level, together with a top∞ list, where every user's time for that level is shown.

How do I get my totaltime in the totaltime lists? Can I just send my .lev files?

You need to upload all your .rec files for the pack you want your totaltime in. I don't accept .lev files for anything. After you have uploaded your replay for every level in the pack, your totaltime should show up in the list.

How are the replays automatically recognized? Can I add this to my own site?

Every replays contains extra information, like for instance what level it is driven on. Using a script it's possible to extract that information to get the exact time of the .rec file as well as the level file it's driven on. If you'd like to add this to your own site, you need to be able to understand php (or alternatively port the code into your preferred language, as long as it can read binary files). Here is the source code for the script. Big thanks to milagros for making me the code in c++, and also to Viper_KillerGuy for helping me port it to php code.

Can you add the possibility to <insert feature here>?

Depends on how hard this feature is to implement, but as long as I don't think it's downright silly, it's quite possible. Either tell me your suggestion in IRC (skint0r @ IRCNet), or write it in this topic on Mopolauta.
