ANYONE WHO'S HAD THE luxury of full Internet access knows the World-Wide Web is great browsing territory. But for those who want to wander the Web and don't yet have access through a SLIP or PPP connection, there's now another way in: it's SlipKnot, a shareware browser ($29.95) that lets you do almost everything Netscape and NCSA Mosaic do-just at a slightly slower speed. (For information, send a blank e-mail message to slipknot@micromind .Corn). A top commercial browser for SLIP or PPP connection is Internet Chameleon (by NetManage, $199). Besides a slick browser, it includes a newsgroup reader, mail, FTP, Gopher and other Net utilities-and a quick way to sign up for full access.
