Hello! There are two ways I know, but there may be others, I'm not sure.
One way is to join their community, as shown in this guide http://ofurotaimu.dreamwidth.org/84319.html Community updates can be sent in a daily newsletter of sorts (called a Nico Report) to your email. Also if you install Nico Live Alert, you can be alerted for namahousous.
Another thing you can do, is if you can find that person's profile on Nico Nico Douga, you can actually put them on your "watch list". Their updates will be shown on your Watch List on your Mypage. For example here's Gero's profile on NND: http://www.nicovideo.jp/user/190917 . To add him to your watch list, click on the button that looks like this http://i43.tinypic.com/23wm9hf.png . To go to your Watch List on your Mypage, go to this link http://www.nicovideo.jp/my/watchlist . When he uploads a video for example, it will appear on this watch list.
Personally I find it easier to follow utaite on Twitter to keep track of them, but this way works too :)
