I'm new to BBO and have not played competitively for 30 years. In my pursuit to refresh my understanding of SAYC and 2/1 GF, I'm doing a lot of kibitzing and reviewing players convention cards. Hopefully, I can discern from this what are the most common conventions being played. My survey of convention cards has proven to be fruitless as I'm constantly running into unfamiliar acronyms. Is there a comprehensive list of acronyms on the forum or on the web?
Here are some examples of such stumbling blocks.

At the bottom of the special doubles box there is a line where I have seen the following entries: "Rox" or "Eq Lev Cov" or "(ELC)X". What do these mean? I hesitate to message a player while I'm kibitzing for fear of interfering.

Thanks!

Not sure about a general list, but the latter two are equal level conversion doubles.

What evil person decided that cov is an illuminating contraction, rather that, say, cnv.

As it is, my first reaction is that it's a contraction of cover.
