3. Modify the menu that the user sees, when the website is first loaded, so

that the user is able to see a link that says Show all posts like the figure

below

Clicking on the link should show the user all the posts that have been

added to the system by various users and the time at which they added

it. Note: the user should not need to login for this. Create a template

called allposts.html for showing the result. The resulting page should

look like below

4. Add Javascript to the appropriate file (myjs.js), such that when the user

goes to the signup link and tries to register, it checks the password field

for the following features:

(a) The password must be at least eight (8) characters in length

(b) The password must begin with either a number (0 ? 9) OR a capital

letter (A - Z)

The Javascript should check the password field, when the user finishes entering

the password and goes to the next field (which is Repeat Password).

The Javascript should check condition (a) before condition (b), and it

should alert the user at the first failure. The screen should look like one

of the screens below (depending on the condition that failed)

5. Add a feature to the site, so that when a user logs in, they can see another

option, both in the menu at the top as well as on the webpage, to see

their own previous posts. Create a new template called prev posts.html

to show the posts. The screen should look like the one below:

Clicking on the Show previous posts link should show the user only the

posts that they have made, themselves. If there are no posts made by the

user, the screen should look like below:

6. Modify the existing code for Write a micro post so that when the user

finishes writing the post, they are taken to the screen that shows their

previous posts. For example, if I write a new post saying “My second

post”, then clicking on the Add Post button should take me to the Show

previous posts screen. The screen would then look like below:
