Like I said in the question. ;)

Other websites support video without plugins

...to select page number in addition to previous/next buttons in our favorite videos list

+1

adding friends to view private home made amateur films

kind of like live web cam but no cost.the girls on those dont act like they like what there doing this is for people who actually like to fucking all the time without the cost of paying

In addition to search terms("MILF," "Creampie," "Amateur," etc.) Have a dropdown box where users can select desired physical criteria of persons in videos. EX:
Person1: |Sex|Ethnicity|Haircolor| [+]

If users want to search for videos of more than one person, clicking the [+] button will add another set of dropdown boxes. This way, users can search for desired content quickly.EX:
A search with:
[Female, asian, black]
[Female,Black, Black]

would display content of an asian female with black hair and a black female with black hair. i.e. interracial lesbians

Some search terms get many results. Sometimes, a user doesn't want to watch what everyone else has seen. Another reason to implement this idea is that the upvote percentage of content with small number of total votes changes drastically if a user downvotes the content. Lastly, this idea should be approved because it is almost effortless to implement. i.e., This site already sorts content in descending order, so the opposite could be easily done (You could even put it in a frame along with the planned category and duration filters)

Add a "Next" button that would generate similar videos. For example, a Lisa Ann video would generate similar MILF vids. Upvote if you figure the feature to be handy. Thanks.

There are several redundant tags on the site, e.g., "exgf," and "exgirlfriend," "blonde,' and "blond," etc. I would ask the mods/admins to merge the repeat tags, or implement a way for users to do it themselves

When browsing tags, allow for multiple words in one tag, this would allow for ease of use in finding desired content, and reduce amount of data transferred on Tube8's end.

For example: "fingering". Fingering what; Asshole? Pussy? Or "Big"; Again, Big Tits? Big Cock? You get the picture.

why can we not send messages to each other

Ask/poll users in what kind of new categories they might be interested in. There could be more female only or male only categories, or there could be a bisexual category etc.

Change the rating system, so many good movies have 5 votes and if one is negative it becomes 80% and then becomes lost.
A percentage scale or star system may be more accurate than thumbs up or down.

Based off of your favorite videos and most recently watched we should have an area which recommends us new videos that we have not seen before similar to what we might like.
