I didn't think posting that names script was bad. You did mention that it can lag & that you use it when the scores show up between games. I think that's fair warning enough.
I think it depends on the server speed whether or not the server will lag. I've seen people use these type of scripts many times & I've never seen a problem with it. I can see how it would be a problem on slower servers though.
I thought about doing something similar, but it seemed like too much work. I did make a script that toggled models without knowing how it would affect servers too. I learned pretty quick though, lol.
