I know this is two years old but I figured I'd post.
We're trying to get Delta Sigma Phi back up at SHSU. Right now we're recognized by the university as Delta Sigma but we don't have an official chater from Delta Sigma Phi due to the number of members. I believe it was started back up in Spring of 2005 and we've grown to about, eh, 15 members so far.
