Signing day is underway ...

National signing day is finally here. We've talked about it plenty the past few weeks and throughout the season. The nation's high school players can now begin signing letters of intent and make their way to campus this summer for fall camp.

A few are even already enrolled.

We've got plenty of coverage for you on all the ESPN platforms throughout the day. Our ESPN.com recruiting team has plenty of coverage for Wednesday, including a rundown of the nation's top classes, breakdowns of recruiting classes within the conference and a look at where the nation's top undecided recruits will sign.

Two teams in the Big 12 are on their list of schools who look like they'll hit late speed bumps in the recruiting game, too.

ESPNU and ESPN3.com will have signing day coverage from now until 7 p.m. ET Wednesday night, so be sure to tune in there.

Want the latest updates throughout the day? Chat all day long with our recruiting experts, who'll provide them and answer questions in a live chat that will continue until 7 p.m. ET tonight.

We'll keep you updated on the blog of any major developments, and we'll break down every class in the Big 12 on the blog Thursday.

We'll have plenty more right here throughout the day, so keep checking back.
