Missing unusual slider(Ya know how in the top left corner there's a little "plus" sign?) Worked in other huds but doesn't show up in yours. Any advice?

IE. Nope, volume mixer is fine.

Tried a center today, did not work. (Sowwy for late replies) Any other suggestions?

No tf2 center ready up sound? I want to play mge n' shit but I don't want to miss out on the lobby. Any suggestions on how to fix this? Thanks :)

Hey guys! For the past few weeks, I have been dying to get started into competitive Team Fortress 2. While I don't exactly stomp on pubs, I can definately see that I have gotten better than I was before. Even a 1 kill death ratio doesn't satisfy me (yes I care about K:D, this is pubbing :o). Anyways, I think I want to get started into competitive because lets face it.. there's only so much excitement playing in pubs. I am afraid to use my voice because I am pretty young compared to these players and in YouTube videos, I have not heard a single person with a voice like mine speaking in Mumble. Anyways, how do I get started? Sure there are over 8,999 threads out there but do I have to look for a group that is willing to check me out? Sure I could spend thirty minutes reading guides and how to get started, OR I could be lazy and wait for the comments that I receive tommorrow morning if anybody cares about responding to this post. So just a few questions.
1) Do I have to be accepted by a group or do I have to play a couple of mixes or pugs?
2) Do North American players accept young peo-CHILDREN? I would rather not give out my age but I am a teenager..
3) Will I have to practice my non-pubertied nuts off doing rollouts and MGE rounds?

I'm sorry if this doesn't make any sense. I do hope that this is quite.. legible(?) to any adults reading this. Thanks for reading ;)
