Excellent!
You're starting to sound like a techie now! Yes, you can buy an Ethernet nic card for your current computer. See the second paragraph in post #51. You'll need to install the drivers that come with the nic card to get it to work on Windows 98 but that shouldn't be difficult. You may want to check ebay for the products I linked to in my posts as well.
I'll have the Best Buy geeks install what is needed. Ironically I used to sell Best Buy Golf Shirts (with the Best Buy logos) over a year ago on eBay. Size 5X. They really looked great. A Best Buy manager e-mailed me and asked how I got them since my prices were so low. They only cost me $2 each. I liked them so much that I bought an XL size Blue one for myself. Still have it.
