How many WFNNB credit cards can I have?

[FICOMari]

I currently have three WFNNB cards but would like to try for a Bealls card which is part of the WFNNB family as well. Does anyone know if WFNNB puts a limit of how many cards one can have?

I have 4--Chadwick's, Brylane, Metrostyle and Newport News.

Had Chadwick & Metro since 2006 and they've  been pretty generous with CLs, (for catalogue cards)  automatic and requested.  Started at $250, now at $1450 and $1380. Had NN and Brylane since 2007 and they're at $670 and $400.
