I have trouble seing the site. Everything is too big or too small.

The Protech-Oxyplast forum was designed with a screen resolution of 1024 x 768. However, it is still usable at lower or higher resolutions.If the text on the site appears too big or too small, you can adjust it using your browser's text adjustment function.
To adjust the font size in Firefox, go to View -> Text Size and choose Increase, Decrease or Normal.
To adjust the font size in Internet Explorer, go to View -> Text Size and select a font size from Smallest to Largest.
