I hate to see error messages in my log and had several pop up with your skin related to some typos...
I hope you don't mind a suggestion to look at these:
In 'Skins\Rain Forum\style.inc':
You missed a closing variable hash # on line 105 causing 'Formula syntax' errors. Shape2=Line (2*#formScale#),(1*#formScale#),((#formWidth#*#formScale#)-(7*#formScale#)),1 | Extend widthAndColor2
Line 81 has a section name [MeterBG] but your other skins are using a section variable expecting [MeterBackground:W] causing 'Formula syntax' errors. I renamed the section: ; [meterBG]
In 'Skins\Rain Forum\rainforum.ini' you have unmatched brackets on lines 1476 & 1477 causing error messages; an extra bracket at the beginning of the formulas. X=(([MeterBackground:W]/10)
Also in that file, longer THREAD titles overlap the REPLY column. I would suggest changing the clipping value on line 64 from W=(220*#formScale#) to W=(170*#formScale#)
Now there were no annoying errors message and I can really enjoy your skin
Thanks for sharing a very nice skin!
