Firstly, how do I get the current version name that will be returned by GetPlayerVersion?

Next, if a person client version is outdated, will they be able to connect to my server?

Lastly, same question but this time, if the person's client has a newer version than my server

If they have a lower version then your server they wont be able to connect and the other way around.

GetPlayerVersion gets the players current SA-MP version and you can return it in a string.

Then I just wasted my time making a version check script? Crapping nice. What if I want them to see a custom message before they get kicked?

not exactly, there's 0.3x, 0.3x R1-2 and 0.3x R2 all which work on 0.3x servers
