Latest Attempt to try and get some C4d into some sigs, having trouble finding good effects, if anyone has a link to a good pack let me know ive downloaded a few packs but ended up deleting them because i couldnt open them, .rar files dont seem to have anything to open in on my mac.. Oh yea C & C also please
Get winRAR. It's free. Can't comment on the tag cuz you saved in JPG and it looks blurry on my screen.
It's probably just low quality. Save your sigs as .png . As mantis said, use winRaR to open .rar files, simply right-click and extract.
