this is my text tip tht never put a text in the middle of ur sig or tag....and also blend your text it! ^_^
you could also try putting the txt layer in softlight or overlay mode and play with the opacity settings
-Change Opacity -Outer Glow (sometimes good) -Blend in -Bevel and Emboss for thick text -Only do Bevel and Emboss if you know what your doing It really kind of matters how your making your siggy.
